The application of the proposed risk management model allows one to effectively reduce the risk of basic events occurrence and provides a remarkable reduction of the risk of the top event’s occurrence. The practical application of the proposed risk management model for HDD projects was shown in an example. The following types of risk response strategies were applied: passive and active risk retention, risk transfer, risk elimination, and risk cause or effect reduction. Overall, 147 risk remediation strategies for all the identified HDD risks were proposed. Horizontal directional drilling is a trenchless method of installing a pipeline underground below identified features (obstacles) without disruption to any of. Fuzzy fault tree analysis, fuzzy weighted index, and a risk response matrix supported the risk management process. River crossings, dune crossings, landfalls and outfalls, crossings of infrastructures: HDD is ideal for complicated projects that require technological mastery. From civil and environmental services to mechanical pipeline design, we provide HDD design services to fit your project and get you around obstacles to a. By utilizing our directional drill and pipe fusion services, we have performed numerous slip line projects that have met or exceeded our clients expectations. In this paper, a new model based on proactive and holistic approaches is presented, which is an extension from traditional risk analysis toward complex risk management in HDD projects. Both risk analysis and risk management are key tools helping to meet today’s challenging trenchless construction project demands connected with quality, deadlines, costs, and legal issues. What is horizontal directional drilling Horizontal Directional Drilling (HDD).

Nowadays, horizontal directional drilling (HDD) technology is one of the most popular trenchless construction methods for installing pipelines under obstacles. Contact Dave Cass for information on Horizontal Directional Drilling projects.
